BALING-PRESS.

SPECIFICATION formingpart of Letters Patent No. 712,208, dated October 28, 1902. Application filed November 26, 1901. Serial No. 83,796. (No model.)

To a/ZZ whom t may con/cern.v l

Be it known that I, PLIN C. SoUTHwIcK, a citizen of the UnitedStates, and a resident of Sandwich', county of Dekalb, and State 'of Illinois, have invented certain new and useful Improvements in Ealing-Presses, of which the following is a specification, and which are illustrated in the' accompanying drawings, forming a part thereof.

The invention relates to baling-presses inll which power is applied for advancing the compressing-plunger through the medium Aof' a toggle-joint.

In the machine shown and herein described there is present the common form ofoscillating feeder for forcing the charge into the compression-chamber upon the recession of the plunger, the invention consisting in so connecting the feeder With the compressing mech-V anism that the recoil of the latter is cushioned by the feeding action.

The invention comprises the arrangement and combination of parts hereinafter fully described, and particularly designated in the claims, and which are illustrated in the accompanying drawings, in Whichl Figure 1 is a side elevation of a portionofa baling-press, showing the packer audits -connection with the operating mechanism.

Fig. 2 is a plan view of the same. Fig. 3 is a detail side elevation ,of the packer, and Fig. 4 is an end view of the same.

In the drawings there is illustrated the common form of chamber-body 9, having a top feed-opening; the reciprocating compressingplunger 10; a shaft 13, having keyed thereto and oscillating above the same a member 11, to which is connected the other member, 12, of lthe toggle for operating the plunger,the member 11 and the end of the member 12 oscillating over the shaft during the operation of .the press; the chain 14, secured to one of the toggle members and turning about a sheave 15, by means of which power is applied for straightening the toggle; the chain 16, secured to a cam-crank 17, fixed to the shaft 13 and turning about the sheave 18, by means of which the compressing-plunger may be positively withdrawn, and the feeder-arm 21, carried by a rock-shaft 19, jonrnaled across the top of the body 9 just back of its feedopening, the feed-arm carrying the plates 22 23 for forcing the material into the compression-chamber. v l

A crank-arm 24 is xed upon the shaft 19 and a crank-arm-26uponthe shaft 13, and a' rigid pitman 25 connects the'twocrank-arms.Y

These arms are so disposed angularly that when the compressing-plunger is retracted the feed-arm is advanced. As in the machine shown the shaft 13 turns approximately half around, while the shaftj19 makes butapproXimately a quarter-turn, the crank-arm 26 is v considerably shorter thanthe arm 24.

A plate 27 projects backwardly from the top of the plunger, as usual,andas the latter advances a new charge of material is thrown upon this plate. Upon the recession of the plunger the feeder descends and forces the new'charge into the compression-chamber andV is carried down thereupon positivelyr by the crank-and-pitman connections referred to, so that the resistance of the material is borne back to and sustained by the toggle andin opposition to the force retracting the same.

In machines of this type when the shorter member 11 of the toggle passesthe perpendicular on recession it falls back. heavily, to the detriment of the mechanism. lCushioning-springs have heretoforevbeen depended upon to take up this strain; but by the construction here shown and. described these springs are dispensed with and the elasticity of the material itself' aords the'necessary cushionin g action, While the positive application of power to the feeder insures the packing of the charge well down into thecompression-chamber.

I claim as my inventionv 1. In abaling-press, in combination,a plunger, a rocker-shaft, a toggle connecting the rocker-.shaftand theplunger, one member thereof being a crank-arm of the shaft and oscillating over the shaft, a chain or cable for receding the toggle, an oscillating feeder having a crank-arm, a crank-arm on the rocker-shaft, and'a pitman connecting said two last-mentioned crank-arms, the parts being so disposed that the feeder is advanced as the toggle recedes.

2. In a baling-press, in combination, a baling-chamber, a plunger reciprocating therein, a rocker-shaft, a toggle-joint connecting the IOO plunger and t-he rocker-shaft, one member shaft being so disposed that the feeder adthereof being keyed to and oscillating above Vances as the plunger recedes.

the shaft, anv oscillating feeder, a crank-arm A keyed upon the 1ocker-shaft, a erank-arm for PLIN C' SOUTHWICK' actuating the feeder, and a pitman conneet- Witnesses:

ing the two crank-arms, the two crank-arms J. B. TUCKER,

and the toggle member attached to the roeker. W. HINMAN.
